The manageiq-ssh-util library is a wrapper library around net-ssh. Its main benefit is that it automatically handles channels and logging for various states when running remote commands. It also automatically handles terminal passwords and running commands via sudo, as well as automatic retry for host key mismatches.

Some differences with the original MiqSshUtil library include:

  • The name has been changed and scoped under the ManageIQ namespace.
  • The ability to override the default value for the :use_agent option.
  • Bug fixes for the on_extended_data ssh channel.

For details of the original bugs (and fixes) please see

The remaining differences are internal refactoring updates.
